Hi. Since you haven't attached your full dcs.log yet, I'm taking a wild guess here. However, your .crash log contains three different messages that often points to a RAM issue:
0x00000000002C32E9 (nvwgf2umx): NVENCODEAPI_Thunk + 0x1894A9
0x00000000000C569A (nvwgf2umx): (function-name not available) + 0x0
0x000000000045C585 (nvwgf2umx): NVDEV_Thunk + 0x16F1A5
Please try these steps:
In your PC BIOS, ensure your XMP mode is not "Auto". Simply choose another XMP profile. If no XMP mode helps, disable it and retry DCS.
Still crashing? Create a bootable MemTest86 device (USB drive or CD) : https://www.memtest86.com/download.htm
Boot up the MemTest86 device on your PC. When the MemTest menu appears, press “S” key to start the memory test. If you get no error after a one-hour test, consider that your RAM is OK. Below is an example of a memory issue as seen in MemTest86.
If an issue is found, shut down your PC, open it, and kindly remove the RAM sticks from their slots before re-seating them, then re-test your RAM (sometimes, all you need is static electricity from the sticks, and this is how it's done).
Still crashing? You’ll probably have to replace the faulty RAM stick.
